6. Radio antenna apparatus for ready mounting on the outside of anautomobile in a manner to provide the advantages of an outside mountedantenna and yet without defacing normally visible portions of theautomobile body, said antenna apparatus including a metal body portionhaving an axial bore therein, insulating means providing an insulatinglining for said bore, portions of said insulating means extending out ofeach end of said bore, an aerial supported by said insulating means andextending axially above one of said insulating means portions, anextension of said metal body portion intermediate said insulating meansportions and extending to one side thereof and an apertured mountingmember connected to said extension.
